Honestly, grab the Fujifilm XF 18-55mm f/2.8-4 R LM OIS and dont look back. I took this exact kit to Tokyo last year and was super satisfied with how it performed. It is incredibly sharp for a kit lens and the built-in OIS saves you in those dim alleys when youre shooting handheld at night. The zoom range is perfect for street photography and landscapes without being too bulky on the X-T5 body. Just remember to keep your aperture around f/5.6 to f/8 for the best edge-to-edge sharpness if you're doing scenery shots. It works well and I really dont have any complaints packing light. If you need help with custom film simulation settings for your trip, just let me know.

> I am totally overwhelmed by all the lens options. Totally get that, honestly. If you want a cheaper route, check out the Sigma 18-50mm f/2.8 DC DN Contemporary. It is super tiny and light, which is perfect for walking around Japan all day. Just be careful since it lacks OIS compared to the Fuji stuff. Another solid pick is the Fujifilm XF 18-135mm f/3.5-5.6 R LM OIS WR if you need more zoom range, but it gets kinda heavy. Good luck with the trip!

Saw this earlier but just now getting a chance to reply. Since you are going to Japan, you really want something that handles everything from tight street shots to scenery. I personally rely on the Fujifilm XF 16-80mm f/4 R OIS WR for travel because that extra reach on the long end and the wider 16mm start makes a huge difference compared to the standard kit lens. Its not the fastest lens out there, but for daytime travel stuff, the constant f/4 aperture is super predictable and easy to manage. Plus, it has weather sealing, which is a massive relief if you get caught in a downpour in Kyoto. Here is why it works for me:

• The 16mm wide end is perfect for those massive temple gates.
• Stabilization is solid, so handheld shots at night come out way clearer than you would expect.
• The build quality feels sturdy without being a total brick in your hand. If you want to do some homework before your flight, check out the reviews on the Fuji Love website or look at the dedicated user groups on Flickr where you can filter by lens to see real world shots. Honestly, just pack light and enjoy the trip, you really cant go wrong with this zoom. Let me know if you need help finding a good strap for it too.

Stumbled upon this thread a day late but just had to chime in. Honestly, I get the excitement, but be careful. I brought the Fujifilm XF 18-135mm f/3.5-5.6 R LM OIS WR on my last big trip because I thought it was the ultimate all-in-one solution for Japan, and well, it was kind of a letdown. Unfortunately, I had issues with sharpness at the long end, and the size felt pretty clunky on my X-T5 after a few hours of walking around. It just wasn't as reliable as I expected for the price tag. If you really want one lens, I think you should prioritize build quality and a weather-sealed body so you dont have to worry when you get caught in a sudden downpour. Here is what I would do if I could go back:

• Stick to a prime if you want the best images, like the Fujifilm XF 23mm f/2 R WR. It is small, weather-sealed, and super reliable.
• If you really need zoom, just look at the Fujifilm XF 16-55mm f/2.8 R LM WR. It is heavier for sure, but the image quality is actually consistent, unlike the cheaper zooms that made me miss my shots. Just be careful lugging around too much weight, my back was killing me by day three. Have an amazing trip tho, Japan is incredible regardless of what you bring!

Quick reply while I have a sec... @Reply #4 - good point! On my first extended trip abroad, I made the mistake of buying purely based on spec sheets rather than real-world ergonomics. The gear looked amazing on paper, but after carrying it for ten hours straight through crowded transit stations, the weight distribution completely wrecked my shoulders. Switching to a more balanced, weather-sealed prime and standard zoom combo later on changed everything. When comparing different system brands, I learned that the body balance matters way more than theoretical sharpness charts. Reliability under sudden heavy rain in mountain regions also taught me to prioritize solid build construction over getting the absolute fastest maximum aperture.
